2 AA Battery Powered

The First Alert Cat. Nos. CO400B and CO410B are battery operated, 3V (two 1.5V

AAbatteries) single station carbon monoxide alarms specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories and other multi-family dwellings as defined in standard NFPA 720. Models CO400 and CO410 comply with UL2034, NFPA 720 and other agencies that model their codes after the above agencies.

First Alert CO400B and CO410B feature an electrochemical CO sensor, an 85dB horn a silence feature and a red LED that blinks to indicate unit is receiving power. The front access battery door allows battery access without removing the unit from the wall. The low power warning indicator will cause the alarm to “chirp” when the batteries need replacing. The low power warning indicator can be silenced for up to 8 hours. An Alarm Action Chart identifies action steps to take if unit is in alarm. First Alert CO410B also features a backlit digital display that shows visual confirmation of CO levels and has Peak Level Memory, remembers and displays the highest levels detected when the Peak Level button is pressed. Backlight illuminates only when any button is pressed or unit is in alarm. Includes mounting anchors and screws.

C0400B, C0410B specifications

The First Alert C0410B and C0400B are advanced smoke and carbon monoxide detector models designed to enhance household safety. These devices incorporate cutting-edge technologies to provide reliable alerts in the event of smoke or carbon monoxide presence.

The First Alert C0410B is a combination smoke and carbon monoxide detector. One of its main features is its photoelectric smoke sensing technology, which is known for effectively detecting slow-smoldering fires, such as those caused by burning furniture or bedding. This type of sensor reduces the likelihood of false alarms triggered by cooking, making it a practical choice for family kitchens. The unit is equipped with a voice alert system that provides specific announcements, such as "fire" or "carbon monoxide," allowing users to respond appropriately to the danger at hand.

Another significant characteristic of the C0410B is its digital CO sensor, which continuously monitors the levels of carbon monoxide in the environment. This feature is crucial because carbon monoxide is a colorless, odorless gas that can pose serious health risks. The detector's LCD screen displays current CO levels in parts per million, assisting users in understanding their air quality.

The First Alert C0400B is a dedicated carbon monoxide detector. This model features an electrochemical carbon monoxide sensor that provides accurate readings and rapid response to CO presence. The C0400B also features a loud, 85-decibel alarm, ensuring that the alert can be heard throughout the home, even during sleep. Both models come with battery backup systems, ensuring they remain operational during power outages—a critical feature for safety.

Installation for both detectors is straightforward. They come with mounting hardware and can be placed on walls or ceilings, with the recommended installation locations being near sleeping areas and potential CO sources, such as gas appliances or furnaces.

First Alert has also focused on user-friendliness in the design of both models. The detectors include a test/silence button for easy functionality checks, and their modern design allows them to blend seamlessly with various home decors.

In summary, the First Alert C0410B and C0400B are essential devices for safeguarding homes against the dangers of smoke and carbon monoxide. With their advanced sensing technologies, clear alerts, and easy installation, these detectors provide peace of mind to families, making them valuable additions to any home safety plan.
